The shields are from one of the more modern kits. Prices for the old shields on eBay are ridiculous. I'm planning on doing the same for my Chaos Thugs and Skeleton Warriors because I have piles of newer shields in my bits box. The handful of old school shields I have are reserved for my Chaos Warriors!
The building is scratch-built from foamcore and balsa wood with the addition of some old Mordheim bits.
